1.dense fused alumina-zirconia 2.a high hardness, 3.high toughness, 4.good grinding performance characteristics

dense fused alumina-zirconia PROCESS OF PRODUCTION AND APPLICATION

zirconia alumina is produced in a high temperature electrical arc furnace by fusing zirconium quartz sand and alumina. zirconia alumina is characterized by hard and dense structure, high toughness, good thermal stability. It's suitable for manufacturing large grinding wheels for steel conditioning and foundry snagging, coated tools and stone blasting, etc.
